Mr. Smilie - Happily Homicidal Computer Virus - Unstoppable, Unflappable, Unpredictable
The lack of a physical body doesn't slow you down - you're a digital menace! Your purpose is clear - heck, it's
written in your code - wreak havok! You spread like wildfire, taking out computer systems and cutting
loose with reckless abandon, sparking fires, flooding compartments, targeting missiles, whatever comes to mind!
And when the fun winds down and the heroes are closing in, you simply key up your current system's self-destruct!
After all, what do you care? You're backed up on disk!
